* The principal' object of this invention is to provide a windowfastener which may be adjusted to permit a partial opening of the windowsashes for the purpose of ventila 'tion' without allowing unauthorizedentry.

Another salient object ofthe invention is toprovide a window fastenerfor securing a Window in closedlposition, in partially opened position,or which may be adjusted to permit the full opening of the :window, asthe occasion may require. 7 l

1 Other objects consist in the provision of a window fastener which willbe compara tively easy to install, positiveacting in operation,and'which because of its sturdy construction, will be exceedinglydurable.

In the drawing Figure 1 represents a front elevation of the novelfastener, associated with the sashes of a window and in position forsecuring the said sashes in window closed position.

Fig. 2 represents a vertical sectional view through a conventionalwindow structure taken substantially on the line 22 of Fig. 1 andshowing in edge elevation, the window fastener in window securedposition.

Fig. -3 represents a horizontal sectional view taken through the deviceapproximately 'onthe line 3-3 of Fig. 1, but showing the v swingable armmaintained against the sta- 35- tionary bar so as to permit the freemovement of the sashes without interference by the fastening device. Y I

ti'onary bar. I Referring to the drawings wherein like numeralsdesignate like parts, it'will be seen, that the improved fastener is tobe associated with a window'con s'truction'of the type including theusual rectangular "frame5 in which the upper and lower sashes 6 and 7amslidablep i i The novel fastener includes an elongated bar 8 providedwith openings 9 (preferably tweenthe swingable arm and the" Sta icountersunk), forxreceiving'screws in; the,

attachment of thebar tothe upper sash 6. This bar is'adapted to be;attached to'theup-- per sash at the inner side thereofand ad-'- iacentthe pperrail ofthe 'lower'sash-7'.

The upper end of the bar is'provided with a pair of upwardly extendinghinge knuck-- An elongated arm11 substantially longer thanthe barS isprovided at oneend with a pair of hinge knuckles 12.- Appin13 is em Theen'dof the arm 11 opposite'fromthe knuckles 12 is provided with atransversely disposed tubular member 16, while a finger 17 is disposed'=later'ally from" the intermediacy of the arm 11 andis bent toward thebar 8 ina manner whereby the same may snap Over the edge of thesaid barto' maintain the arm. snugly against the bar as in the manner shown inFig.3, when it is desired that 'the'fastener be moved" out of Thislatchdevice includes a'base plater18 bent at one'end'to provide} a'depending I flange 19." The intermediacyof the plate disposed upwardlyand formed to provide an elongated barrel and a relatively shorterbarrel 21 alined with respect to the barrel 20, yet spaced a substantialdistance therefrom to permit the interposition of the tubular member 16of the arm 11.

{The plate 18 is provided with openings 22 gh whieh screws y b disposfor securing the plateto the upper rail of the lower sash 7, the flange19 being disposed over the inner side of the said rail in the mannershown iniFig. 2. V a 5 V A bolt is slidably disposed within the barrel20 and is engageable within the barrel 21 and at one end. The bolt isprovided with a projection extendingthrough a longituiil el slot 24 theba el 20 nd thi p ojection is equipped with a finger engageableenlargement 25 The slot 24; is provided with ofise 'ZG or recei ing thesaid pr j t on n maintai ing h o pr je ting to a position with its endlocked within the short barrel 21 and obviously t rough thetubularmember 16, of the arm 11, when said'lnember is interposed betweenthe said barrels 20 and 21- In this mann r the sashes may be securedagainst movement within t rame 5 of th windo I a In order to permit apartial opening oi the sashes for the purpos o n l ion, the

Th arm 11 will be prevent d rom mo g upwardly beyond this point due toits abutmeet agains the stops he sashes may be then mo edto apos tionwhere the upper il, of, the lower sash 7 willab tthe arm'll,

However, when it is des red at he ashes he e -nee to move withouinterfer n e by the ast ning device, the arm is pre sed against the bar8- .0 that the pring catch 17 will engage over the edge of the Said barwhereby it will be maintained in the position hown in Fig. 3-
